Media notes
Individual on the right is long-calling. Crayfish stolen by the individual on the left from a Hooded Merganser lays on the ice between the gulls.
Observation details
Watched one steal a crayfish from a Hooded Merganser, then fly up to about 15 feet in the air and drop it on the ice. The gull came down on the ice and started trying to pick apart the crayfish, but it wasn’t long before this activity attracted the attention of other RBGU in the area. One came down on the ice and long-called in the direction of the individual who had the crayfish. They both flew off a few seconds later, leaving the crayfish on the ice between them. Didn’t stay to see who ended up with the prize in the end.
